HYAPF Series Active Power Filter

Key Features

• Modular design: Compact size, reduced footprint, flexible for design, selection, installation, and maintenance.
• Three-level topology: Loss reduced by 60%, switching frequency up to 20 kHz.
• High-performance control platform: Uses Texas Instruments 32-bit DSP and ALTERA FPGA, forming a strong dual-core architecture with advanced TTA algorithms for harmonic detection. Capable of compensating up to 51 orders of harmonics with detection accuracy up to 0.1%.
• High-speed data acquisition: Integrated dual-channel 12-bit ADC (TI ADS8558) with 10 V input range, sampling accuracy up to 1.25 µs, ensuring precise and stable performance.
• Advanced IGBT module: Equipped with Infineon EasyPAC-IGBT modules, featuring low-inductance design and reduced switching loss. Operating frequency up to 30 kHz with compact size and higher power density.
• Intelligent temperature control: Real-time monitoring of power module temperature. Automatic alarm and shutdown when exceeding threshold to ensure safe operation.
• Digital harmonic suppression: Adopts full-digital algorithm with advanced PR control to reduce response delay (<10 ms) and ensure accurate harmonic filtering and dynamic compensation.
• User-friendly interface: 5-inch LCD screen with multi-language support, 10-point touch operation, real-time display of voltage, current, THD, PF, and other power quality indicators.
• Efficient cooling system: High-performance fans with redundancy and intelligent fan speed regulation for reliable long-term operation.
• Flexible networking and redundancy: Multiple modules can be connected in parallel for higher capacity and reliability. Supports online hot-swapping and redundancy switching.
• Remote management: Supports optional remote monitoring and control. Provides real-time fault diagnosis, system alerts, and maintenance support.
